Manchester United manager Ole Gunnar Solskjaer explained Chris Smalling is still at the Premier League club because his asking price has not been met.
Smalling was left out of the United squad that beat Luton Town 3-0 in the third round of the Carabao Cup on Tuesday.
The 30-year-old defender impressed on loan at Roma last season and the Serie A outfit are understood to want to sign Smalling on a permanent deal, although United are reportedly holding out for an £18 million (€20m/$24m) fee.
